High Temperature Hydrogen Attack (HTHA)

High Temperature Hydrogen Attack (HTHA) is an insidious condition that can occur in process equipment exposed to hydrogen at elevated temperatures (at least 400F or 204C), under dry conditions, when...
Inspection

Inspection is the practice of examining the physical condition of materials, components, or entire pieces of equipment in order to determine if and for how long it will operate as intended. Inspection plays a vital role in any
Mechanical Integrity (MI)

Mechanical Integrity (MI) can be defined as the management of critical process equipment to ensure it is designed and installed correctly, and that it operates and is maintained properly (i.e. no leaks and all elements are fit for service). A mechanical integrity program should...
Nondestructive Testing (NDT)

Nondestructive Testing (NDT) consists of a variety of non-invasive inspection techniques used to evaluate material properties, components, or entire process units. The techniques can also be utilized to detect, characterize, or measure the...

How a Holistic Approach to Mechanical Integrity Drives Value

Sponsored Webinar Replay

Inspectioneering teams up with MISTRAS Group to bring you "How a Holistic Approach to Mechanical Integrity Drives Value," a one-hour webinar presented by Nick Sowa and Ryan Jones.

Webinar Overview

High-temperature hydrogen attack is a damage mechanism that constitutes both a serious concern for asset owners and a significant challenge for NDT inspectors. Small and complex damage such as HTHA drive innovation towards more sensitive and reliable methods for ultrasonic testing.

In this webinar, Inspectioneering teams up with Evident to review some common challenges and key considerations of HTHA inspection using phased array, and explore the potential of recent innovations in probe design and signal processing.
